+project.
+
+Active Resource attempts to provide a coherent wrapper object-relational
+mapping for REST web services.  It follows the same philosophy as Active
+Record, in that one of its prime aims is to reduce the amount of code needed
+to map to these resources.  This is made possible by relying on a number of
+code- and protocol-based conventions that make it easy for Active Resource to
+infer complex relations and structures.")
